Worked for 11 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

   Beg: Seeing 1 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1 arcsec, Clear, Winds Light & Variable
   End: Seeing 1 arcsec, Clear, Winds Moderate

Observing Summary:

A very nice clear night, one day before full moon. Seeing 
was generally pretty good, too! 

No problems with equipment, though I noted in the afternoon that the history
graphs on the mirror AC computer were showing nonsense.  Also,
on slewing to one of my first targets -- a standard star on the
meridian and just north of the equator -- I heard a flopping 
sound like a mirror petal opening.  Nothing seemed amiss - 
I hadn't actually noticed whether all the mirror petals were up
when I'd opened them. Probably nothing needed except to cycle
the covers a couple times to be sure nothing is sticking.

Dome was not centered on contact at the end -- adjusted and
reset the azimuth reading by 0.8 degrees.

This has been an extremely productive run, in part because it's
been so very long (11 nights), and in part because of the 
weather, but largely due to the diligence of the support staff,
which is much appreciated.
